Subject: Low pressure air conditioning sensor 2007 Peterbilt

SE North Dakota
What pressure should the low pressure sensor go off? This sensor will shut the clutch off at 22psi. Thought maybe it was bad the new aftermarket one I got did the same thing. I wants to kick the clutch on and off like every 3 seconds. Thought maybe the system was low so i added another can and it still wants to pull down to about 22psi then the sensor kicks on and off. Also the stand by pressure is at 90 psi once they equalize so i figured there should be enough freon in it. Maybe the aftermarket sensors trip easier. The factory sensor is $150 vs $48. Thanks
